Sorry but I have been forgetting to introduce a local museum in my neighborhood - Osaka Traffic Science Museum(*official English name: Modern Transportation Museum).
Here comes 'Walter HWK509A-2r rocket engine for Me163B circa 1943' first.
This is not replica but real one which was gifted by the USAF in 1970 when EXPO'70 was held in Osaka, together with a XLR-11-RM-5 rocket engine for Bell X-1.
This is Nakajima's Homare(Ha-45) aircraft engine though terribly damaged.
3rd photo is a montage with my 3d CG work to show this engine's original appearances.
Sorry if you should be complicated.
This is an attempt...
Ha-45 was mounted on the army Type 4 fighter(Ki-84 Hayate for the allied code name Frank), the navy N1K2J Shindenkai as 'Homare' for code name George and some other navy bombers.
